Recently, the Naval Nuclear Laboratory completed the initial thermal-hydraulic performance testing of a CompRex heat exchanger and provided test results to CompRex.  The test results exceeded the expected design performance and provide additional proof that the CompRex design and construction methods are suitable for producing commercial size heat exchangers for supercritical CO2 service.

In August 2014 CompRex LLC (De Pere, Wisconsin) was awarded a contract to design, engineer, fabricate and test high pressure, diffusion bonded stainless steel heat exchanger for CO2 power cycle development. Today CompRex announces that they have passes a significant mile stone with the successful hydraulic pressure test of a fabrication demonstration unit representing the intended heat exchanger. A representative scaled-down unit was manufactured for pressure testing. Test results showed that the unit exceeded the expected burst pressure for the design.
